Naturally, energy efficiency is important. But when making your selection, remember low operating costs are little comfort if service and repair bills are high. Don't be sold on energy efficiency alone. 

Rheem is the only manufacturer to install the Compliant Scroll® Compressor, the industry best, in its entire residential heat pump line.

The Department of Energy requires all air-conditioning and heating equipment manufacturers to evaluate and rate the efficiency of their equipment on a seasonal basis. These ratings are known as the SEER or, Seasonal Energy Efficiency Rating, for air conditioners, and the HSPF or, Heating Seasonal Performance Factor, for heating equipment. 

Heat pumps use both numbers. The higher the SEER or HSPF rating, the more efficient the heat pump. High-efficiency units cost more. But since operating costs are lower, the payback period may be shorter than you realize. A high SEER/HSPF heat pump also can add value to your home which is important to today's energy-conscious home buyers.

Absolutely. Look for features such as a louvered, galvanized steel cabinet to protect the condensing unit from outdoor hazards. And make sure the cabinet is powder-painted with a high-quality enamel for improved durability and appearance.

With some units, the outdoor fan can be a bothersome source of noise. Rheem units have a grille design that minimizes air restriction which allows the fan to operate more quietly. Also, the fan is mounted on the underside of the grille. This protects it from the elements and it directs airflow upward, away from plants and shrubbery.
